Class MPSCNNDepthWiseConvolutionDescriptor

  • All Implemented Interfaces:
    NSCoding, NSCopying, NSSecureCoding, NSObject

    public class MPSCNNDepthWiseConvolutionDescriptor
    extends MPSCNNConvolutionDescriptor
    MPSCNNDepthWiseConvolutionDescriptor can be used to create MPSCNNConvolution object that does depthwise convolution Depthwise convolution applies different filter to each input feature channel i.e. no cross channel mixing. Number of outputFeatureChannels can be greater than number of inputFeatureChannels, in which case convolution expects channelMultipler = outputFeactureChannels/inputFeatureChannels number of filters for each input channel. This means channelMultipler filters are applied to each input feature channel producing channelMultipler output feature channels. All channelMultipler output feature channels produced by single input feature channel are stored togather in output image i.e. output[x,y,k*channelMultiplier + q] = input[x,y,k] * filter[k,q] where * here denotes convolution. group must be 1. Weights array returned by MPSCNNConvolutionDataProvier is interpreted as Weights [inputFeatureChannels] [channelMultiplier] [kH] [kW] = Weights [ inputFeatureChannels * channelMultiplier ] [kH] [kW] = Weights [ outputFeatureChannels ] [kH] [kW] Currently only channel multipler of 1 is supported i.e. inputFeatureChannels == outputFeatureChannels API-Since: 11.0
